HBX-OVC-R HB Products Vapor Quality Sensors for Overfeed Systems (Basic Version)

HBX-OVC is thus the first sensor in the world capable of measuring the relationship between gas and liquid a refrigeration system. The sensor measures the degree of dryness, "X", of the gas in the gas pipes, and the value is converted into a 4-20 mA analogue signal corresponding to "X". The measuring range for HBOVC is X = 0.6 to 0.9.

The sensor is available in two variants, "Rod Style" for installation in a pipe elbow and "In-line" for welding into the suction pipe.

The sensor's microprocessor also functions as a controller, enabling the direct control of a modulating motor valve, thereby bypassing the external controller or the PLC. The controller can be set up with all the parameters that are necessary for regulating a modulating motor valve or a stepper motor valve. The sensor is available with a cable for direct supply to and control of the motor valve, or as a sensor where the signal is sent to the external controller/PLC.

Product Features:

• Can also be used in HFC refrigeration systems.
• Measures vapor quality in ammonia refrigeration systems – measures the relationship between gas and liquid (Refrigerant Log Ph diagram).
